Hafnium carbide
Supplier — AvekGlob company — offers at reasonable prices from the manufacturer carbide hafnium. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Technical specifications
Hafnium carbide, obtained by heating powdered hafnium, or hafnium oxide, in the presence of coal, is one of the most refractory inorganic compounds. It is a very hard substance, it has a crystalline structure.
Urgency of application
Hafnium carbide is available in various forms and on request, including discs, granules, ingots, granules, powder, rod and sputtered targets. High purity forms also include carbide powder, submicron powder and nanosized, single crystal or polycrystalline forms. The material is used in hard wear-resistant coatings, in the production of decelerating rods of nuclear reactors, as well as in technological processes of laser deposition.
Chemical composition
The chemical formula is HfC. The degree of chemical purity of industrially produced hafnium carbide is not lower than 99.5%.
Physical and mechanical properties
- Density, kg / m 3 — 12,200… 12400;
- Melting point, 0 C — 3885… 3890;
- Specific heat capacity, J / kggrad — 353;
- Coefficient of thermal expansion, μm / deg — 6,1;
- Coefficient of thermal conductivity at room temperature, W / Mgrade — 9… 17 (with increasing porosity of hafnium carbide, its thermal conductivity increases);
- The size of the granules is no more than 1.25 microns.
Application features
Hafnium carbide is not recommended for use in strongly acidic media. When heated to temperatures exceeding 2000 0 C, the material begins to interact with refractory metals — molybdenum, tungsten, niobium, etc.
Supplier — the company AvecGlob — offers to purchase carbide hafnium in various forms. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
